ultrasonic cleaning fliud,
Verified Purchase(What is this?)
This review is from: JPL Ultrasonic Cleaning Solution 500ml For All Ultrasonic Cleaners (Accessory)
Bought this with my ultrasonic cleaner. It does work, though washing up detergent will also do the job. However you may have more peace of mind using a "designed" fluid for safety.
